2,2-Dimethyl-N-[3-(2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-propionamide. 3-(2-Methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenylamine (0.200 g, 0.780 mmol) was dissolved in Methylene chloride (10.0 mL, 156 mmol) and cooled to 0° C. Triethylamine (0.130 mL, 0.936 mmol) was added followed by 2,2-Dimethylpropanoyl chloride (0.106 mL, 0.858 mmol). The reaction mixture was allowed to warm to rt. LCMS after 30 min indicated mass of title compound. Reaction mixture was washed with water, dried over MgSO4, filtered, and concentrated. HPLC rt=3.436, purity=90%, LCMS=341.2 (M+H).
